1.单张图片修改

import cv2

img = cv2.imread(r"E:\Users\XXXX\Desktop\2.27-15.png")
print(img.shape)
cropped = img[290:900, 320:1300]  # 裁剪坐标为[y0:y1, x0:x1][上方：下方， 左边：右边]
cv2.imwrite("cv_cut_thor.png", cropped)

2.批量图片修改

import cv2
import os

# 原始文件夹路径
original_folder = r'E:\Users\XXX\Desktop\data\test\1'
# 保存的新文件夹路径
new_folder = r'E:\Users\XXX\Desktop\data\test\2'

# 遍历原始文件夹中的图像
for filename in os.listdir(original_folder):
    img = cv2.imread(os.path.join(original_folder, filename))
    # 改变尺寸
    cropped = img[290:900, 320:1300]  #这里是你要转换的尺寸
    # 保存到新文件夹
    cv2.imwrite(os.path.join(new_folder, filename), cropped)
